A mysterious life form known as Savage is attacking the Earth, and there is only one weapon that can counter it: the Hundred. To become a Slayer, a master of military arts able to wield a Hundred, Kisaragi Hayato enrols in the marine academy city ship Little Garden. However, Hayato feels a strange yet familiar sense of incongruity towards Emile Crossford, his room-mate who somehow knows him from somewhere.

Uta, who works and lives in a hotel on Uranus, has always thought that she is different from other people. Whenever she has free time, she sits in front of her computer making things she likes and enjoys herself alone, or goes to cafes alone. One day, she receives a "Future Ticket" - the key to a new life. Despite this, Uta continues to live her life as she always has. However, as the "Star Festival", a festival to commemorate the closest point between Uranus and Neptune, approaches, she meets Paula, a popular influencer from Neptune whom she admires. After becoming close to her, Uta makes a major decision about her life.
